Are those baffles in your sump made of acrylic and your sump made of glass? How tightly did they fit and were they siliconed in? If they are acrylic are they extruded or cast acrylic?
If the baffles are acrylic and tightly fit then it's possible the acrylic swelled as it slowly took on some water causing increased outward pressure leading to an eventual cracking of the glass. Extruded acrylic will take on slightly more water and swell more than cast. Hence the reason baffles should either be made of like materials or not fit too snugly.
